Can the Roku be Remotely Rebooted (via the Network)

Hi:

I would like to be able and log into my Roku unit via a terminal window and remotely reboot it. Example: With a linux system, one can use 'telnet' or 'putty' and log into the machine and remotely issue the 'reboot' command:
(i) How Do I Remotely Reboot Linux System?
(ii) Remotely Reboot a Linux Machine

I would like to know if this is also possible with a Roku?

Thanks
